Shimano Deore XT Race BR-M8100 Rear Disc Brake 2 Piston - BL-M8100 Left Lever

Built for fast XC and trail bikes, the XT M8100 brake pairs the BL-M8100 lever with the BR-M8100 2-piston caliper for sharp, confidence-inspiring control. Servo Wave delivers rapid pad engagement and strong power with a short lever throw, while the I-SPEC EV clamp keeps your cockpit tidy and rigid under load. The lightweight 2-piston caliper brings smooth modulation and easy setup with banjo hose routing and ONE-WAY BLEEDING using Shimano Mineral Oil.
